Worst Comeback Attempts in Baseball History

Spring training provides young prospects from all over the world with the opportunity to prove that they have what it takes to make it in the big leagues.

They're not the only ones with something to prove, however, as veterans coming back from an injury and those who probably should have stayed retired are also on the diamond, hoping for another shot at glory.

More often than not it seems like these attempts are futile, and sometimes the lasting memories we have of these players aren't of what they did in this league—but what they couldn't do.

After hitting 112 home runs during his first six seasons of major league action, one-time All-Star Bo Jackson was forced to sit out the entire 1992 season after sustaining an injury while playing for the Oakland Raiders.

Speed was an asset for Jackson in his earlier years, with 81 swipes prior to his football injury.

In the two seasons he played after coming back, however, he stole only one base and played fewer than 85 games each year.

After a three-year stint with the Houston Astros from 2004 to 2006, Roger Clemens could have retired, but instead made a comeback at Yankees Stadium in May 2007, signing a one-year, prorated $28 million deal.

He would go on to win six games that season with an ERA of 4.18, making for one of the highest dollar-per-win ratios you'll ever see.

Jose Canseco's massive physique may have tied him to speculation surrounding the use of steroids during his career, but Canseco also confirmed it in 2005 with the release of his book Juiced: Wild Times, Rampant 'Roids, Smash Hits & How Baseball Got Big.

Shortly after the release of the book, Canseco began his comeback, starting with the San Diego Turfdogs of the Golden Baseball League.

He wasn't done there, and has since played for the Long Beach Armada (Golden Baseball League), Laredo Broncos (United Baseball League), Quintana Roo Tigers (Mexican League) and last year played for the Worcester Tornadoes (Canadian American Association of Professional Baseball).
